The Handheld PIC18 IDE is an autonomous system for creating, editing, and assembling source files for a Microchip Technology PIC18. Binary output of this process is programmed into a target PIC18 or is debugged at source level, called PP4. The hardware is simple. It consists of a user interface (LCD and keyboard), data storage, and a programming interface. The handy IDE also includes a BF interpreter for writing and executing scripts in BF language. You can use BASIC with the tag-along BASIC interpreter. The device is solar powered with a Li-Ion cell backup.
